Place the butter in a saucepan and melt on medium heat. Butter starts to foam up first, then boil. Stir occasionally. As the water content in the butter evaporates, the fat content of the butter will solidify. You start seeing small brown specks at the bottom of the pan. Remove the butter from heat, and let the butter cool down to room temperature.
¾ cup Butter
In the bowl of a stand mixer set on the whisk attachment, beat the cream cheese until soft and creamy. Then add the room temperature brown butter. Make sure all the brown pieces are added to the mixture. That's all the good part.
8 ounce Cream cheese
Start adding the powdered sugar ¼ cup at a time. Beat well after each addition. Add the vanilla extract.
3-4 cups Powdered sugar, ½ tablespoon Vanilla extract
Now add the heavy cream, one tablespoon at a time. Add until the frosting is smooth and spreadable. If the frosting is too dry, add more cream, and if it is too runny add more powdered sugar.
